    I give it a test:

    root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos) list ltm profile http customer_http 
ltm profile http customer_http {
    app-service none
    defaults-from http
    header-erase Headertest
    proxy-type reverse
}

root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos) list ltm rule http_header_test 
ltm rule http_header_test {
    when HTTP_REQUEST {
        HTTP::header insert "Headertest" "123"
}

    }

    Then test with curl 10.1.1.73 -H "Headertest: 123", from the capture it shows http header Headertest still in the request.

thanks team it seems irule always win. the exact case which indicate me to ask this is : web server in my company doesn't follow HTTP protocol,if it see no accept-coding in request,it will compress response as gzip ,then send back.but if the accept-coding is shdc,web server will not compress. all I want to do is teach web server not to compress ....

 

so : if I disable accepr-codeing in http compression profile,then insert accept-coding:shdc in request when send to server for specific uri list or content list.

 

Does it work?

 

Besides this:I found uri list /content list is not as I expect.

 

in order to make /xyz* work ,it seems I need to add /xyz.* in uri list ,and add content type in content list,so confuing

 

Correct me if I am wrong
